Do You Know What A Dynamic Voltage Regulator Is?

It is essentially a Dynamic Voltage Regulator (DVR) with continuously adjustable voltage. Its core has two types: ring type and column type. The column type core is similar to the general dynamic voltage stabilizer, and is made of silicon steel sheets stacked; the ring type core is made of silicon steel strips. Small-capacity dynamic voltage stabilizers of 20kVA and below mostly use ring type cores; those with a capacity of more than 20kVA mostly use column type cores. In the structure of the dynamic voltage stabilizer, the winding is wound on the ring type core with a single layer of insulated copper wire. The surface of the coil is ground to form a smooth plane, and the brush made of electrochemical graphite is in contact with it. The brush can be rotated and slid on the surface of the wire by the hand wheel, thereby changing the output voltage. For those with a current capacity greater than 10A, two or more brushes are connected in parallel.

Dynamic voltage stabilizers are generally made into self-cooling and dry types. In occasions with particularly large capacity or special use environment, they are also made into oil-immersed self-cooling types.

Three dynamic voltage stabilizers are coaxially assembled to form a three-phase dynamic voltage stabilizer.
